BUOY FOR SUBMARINES.

Specification of Letters Patent.

Patented Nov. 16, was.

Application filed June '1, 1915. Serial in. 31,473.

To all whom it may concern:

Be it known that I, VALTER H. AMBER- onn, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Buoys for Submarines, of which the following is a specification.

My invention relates to improvements in buoys for submarlnes, the object of the invention being to provide .a buoy or buoys which is so connected with the submarine that in the event of accident to the latter which will prevent the submarine from risin to the surface, the buoy or buoys can be re eased and will float to the surface of the water, operating as a signal and also as a carrier for cables connected to the submarine, and by means of which the latter may,

be drawn to the surface.

A further object is to provide an improved construction of buoy for the purposestated, and provide an improved means for inclosing or housing the buoy on the submarine.

A further object is to provide an improved arrangement of cables'connected with the submarine and the buoy or buoys so as to for drawing the submarine to the surface, and which will minimize any possibility of the cables fouling to interfere with the salvage of the boat.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out [in the claims.

In the accompanying drawings: Figure 1 is a view in elevation illustrating my improvements. Fig. 2 is a view 111 longitudinal section of my improved buoy. Fig. 3 is rine.

a view in longitudinal section showing'the buoy in position in its casing on the subma- Fig. 4 is an exaggerated view in longitudinal section showing the fragile covering for the torch endof the buoy. Fig; 5 is a .detail' view showing one of the metal brackets 3. Fig. 6 is an exaggerated view in section on the line 6-6 of Fig. 3. Fig. 7 is a top plan View of the submarine equipped with my improved buoys.

1 represents a submarlne which is providediadjaccnt its opposite ends with metal straps 2 extending around the submarine,

and provided at opposite sides with metal I brackets 3, one of these brackets being shown. on an enlarged'sc'ale in Fig.5.

4 represents my improved buoy which is shown in section in Fig. 2, in which View it will be noted that the buoy is of general cartridge shape having a horizontal. partiftion 5 therein forming an upper chamber 6 which is rendered. buoyant in any ap proved manner, preferably by providing partial vacuum.

In the upper pointed end of the buoy l. locate-atorch 7 which comprises a' metal casing 8 filled with a composition or mate '13 as shown in 3, so that when the buoy rises, it will promptly draw the bar 11 through the fragile cover 9 or else entirely remove the fragile cover so as to expose the composition to the moisture and cause the same to ignite.

As shown clearly in Figs. 1 and 2, I preferably employ two buoys 4, and provide for each buoy a casing 13 and as the buoys and casings are precisely alike, the description hereinafter will apply alike to both.

The casing 13 preferably'extends entirely within the confines of the submarine so as of the boat, and each casing is provided with "a hinged cover 14 normally held in closed to afford little or no resistance to the speed position by a turn button 15 operated by a I crank shaft 16 extending into the boat.

17 is a screw which is mounted in brackets 18 and which at its upper end bears against 3. lug 19 on the 'free end of cover 14, so that by' turning this screw in one direction, the cover can be elevated slightly to admit water to the casing 13. thereby equalizing the pressure on both sides of the cover, and allowing water to fill the casing 13 when the buoy 4 Wlll promptly ascend, causing the tearing or removing of the fragile cover 11,

and elevating the hinged cover 14,50 that the buoy will be free and can rise to the surface as shown in Fig. 1. j-

The s ace in each buoy 4 below partition .5 is-divlded by a longitudinal partition 20 .-vation of the submarine, and-lifting force is thereby equally applied totbeth ends of the submarine to raise the hitter in a horizontal position. When bothbuoys rise to the surface, the salvage of the-submarine is'rendered extremely easy because a hoist may be connected to bothcables and exert a uniwater tight, and as it is necessary to extend the submarine.

form pull at both sides and at both ends of It is'fpreferable to release one buoy at a time to preventfouling of the cables, and if -for any reason one buoy does not work properly, the salvage of the boat can be accomp i Whi'le'the device might'operate i thecasing 13 were not water tight, I be ieve' it a preferable arrangement to render the same the cables into the casings, I have recessed the cover as shown at 2.4, and providepacking material 25 in the recess to engage the cable. i i

It will be notedthatwith my improvements the buoys can be released from inside of the boat, andin the event that the sub marine fails to rise to the surface when de sired, the buoys can be released and will quickly rise to the surface, operating as signals to attract aid and supporting the cables in such position as to permit the submarine to be readily raised to the surface.

While I have described my improvements in connection with a submarine. for which it' is especiallyadapted, yet I do not limit myshed through the single cable. 1

self in that respect, as any boat may be so equipped.

It is to be understood that the buoys will carry relatively small cables, and by reason of their position they permit a heavier cable to be easily drawn through the brackets 3, I

the cable attached to the buoy acting as a messenger for the larger cable.

, Various slight changes mightbe made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth,'but consider myself" at liberty to make such changes and alterations as may, fall within the spirit and scgpe of the appended claims.

.aving thus described my invention, what I claim as new and desire to secure by Let- 'ters Patent is: v v 1. The combination with a boat having casings therein on top of the boat interinediate the ends thereof, and securing de vices on both sides adjacent the ends of the"- boat, of buoys removably supported in the casings, each buoy having two reels and-a cable, the intermediate portion ofthe' cable extending longitudinally of the boat and located in the securing devices on one side, and at its ends secured to the reels, substantially as described. r

2. The combination with a boat having metal bands extending around the same adjacent the respective ends thereof, and metal loops fixed to the bands at both sides of the boat, of two buoys supported by the intermediate portion of the boat, each buoy having two reels, and a cable, the ends of which are secured to the reels of the buoy, and the intermediate portion is located longitudinally of the boatand extending through the loops on the band, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
